DP9501AT
product description
The DP950X0T series is a highly integrated constant current LED power switch. The chip adopts a quasi-resonant working mode without auxiliary winding detection and demagnetization. At the same time, a high-voltage 500V power MOSFET and a high-voltage self-powered circuit are integrated inside, which simplifies the design and production cost of the system. The chip integrates high-precision inductor current sampling technology, can obtain high-precision constant current output, and the output line voltage and load regulation rate are excellent.
DP950X0T integrates complete protection functions to ensure the safe and reliable operation of the system, such as: VDD under-voltage protection (UVLO), cycle-by-cycle current limit (OCP), over-temperature protection (OTP), output over-voltage protection (OVP), CS sampling Resistance short circuit protection, LED open circuit and short circuit protection, etc.
